I do think having readily-available sources on social media posts is something to keep exploring. It's not that we need the government to police the internet - that would get bad real quick. We need these companies, and the government, and all of us, to act as librarians of information, in better accessible ways, so that users can determine where this information is coming from and it has merit or not. I don't have any answer as to how that would be implemented. I don't think we need police. We just need more transparency and information.
